Four-stroke Dirt Bike Mufflers are one of the easiest and most common upgrades to your machine if you're chasing performance gains straight out of the box, True to their name, slip-on mufflers literally slip straight on, and are actually surprisingly easy to install on your bike (check out our handy little how-to video guide down the bottom as we talk you through the process of installing a new exhaust on your bike). These things are almost unmatched when it comes to bolt on power, with some makes and models of slip-on mufflers offering up to 3hp of gains over your stock standard exhaust.

There are a few heavy hitters in the industry when it comes to four-stroke exhaust mufflers - Akrapovic, FMF, Pro Circuit, and Yoshimura are certainly leading the way. These brands work with some of the biggest factory teams and racers around the world to continually develop the very best products possible when it comes to fine-tuning the performance of your dirt bike, and they're certainly not showing any signs of slowing down. More often than not, the very same exhaust mufflers you see on Eli Tomac's and Jason Anderson's bikes are the same ones you can whack straight onto your bike out of the box, so you know you're investing in something that's the real deal.
